Ice patches in the Yukon mountains used to reliably stay frozen year-round. Insects and animals, from beetles to caribou, would seek out these ice patches as refuge from the summer heat. Human hunters followed. This makes those same ice patches excellent places for pre-Columbian archaeologists to look. With each year, and new strata would be added to the ice patches as more snow fell. Dating artifacts found, and tracing development over time, is unusually easy. Unfortunately, those ice patches are no longer reliably staying frozen. As they melt, it is a race against time to find and preserve artifacts before animals and bad winter weather find them first.
